Apple Logic Pro 9 - Manual (Page 1218)

Logic Pro also obeys Full Frame Messages, and sets the playhead to a new location,
without starting playback. Once again, incoming MTC data has higher priority, if
conflicting information is received.
Some synchronizers send Full Frame Messages (instead of MTC) to locate the slave
device (Logic Pro in this case) to a new position, without implicitly starting playback.
This is useful when in Slow Shuttle or Single Frame Advance mode with video machines,
because the slave device is perfectly located, without being in playback mode.
